Sirius Guide: Best Build, Pro Tips, and How to Unlock | Brawl Stars

The 100th Brawler is here, and he's bringing an army with him. Sirius, the second Ultra Legendary and the game's first true supervillain, has officially joined the Brawl Stars roster—and he's already shaking up the meta in a big way . If you're the type of player who enjoys controlling space, overwhelming enemies through sheer numbers, and slowly suffocating the opponent's map control, Sirius is absolutely your style.

In this guide, we're breaking down everything you need to know about Sirius: how to unlock him (yes, there's a free way), the absolute best build backed by stats, pro tips to dominate your matches, and the game modes where he truly shines. Let's get into it.

Who Is Sirius in Brawl Stars?

Sirius arrives with some serious lore baggage—he's Starr Park's first major villain, kicked out and banned for reasons we don't fully know yet, and now he's back for revenge . Unlike the more sympathetic Trunk (operated by revenge-seeking ants), Sirius leans fully into villain territory. But lore aside, what matters is his gameplay: Sirius is a Controller-class brawler with a completely unique mechanic that lets him collect and summon shadows of enemy brawlers.

Think about that for a second. You're not just fighting with your own abilities—you're turning the enemy roster against them. A Frank shadow? That's a tanky frontline you didn't have to recruit. An Edgar shadow? Good luck to any squishy trying to push your lane. This mechanic makes Sirius one of the most oppressive controllers in the game when played correctly .

How to Unlock Sirius

Sirius officially joins the roster on March 5, 2026, but there are multiple ways to get him—some free, some faster . Here's the full breakdown:

The 99 Brawler Win Challenge (Free)

From now until March 5, you can unlock Sirius for free by winning one match with every single brawler in the game—all 99 of them. Heads-up:This requires you to actually own every brawler. No trial versions here. If you're a long-time player with a full roster, this is your path to a free Ultra Legendary. It's a grind, but winning with everyone also lets you revisit brawlers you might not have touched in months .

Sirius Boxes

During the event, Sirius can drop from special Sirius Boxes. You earn these through quests, and here's the good news: he's guaranteed after 20 boxes. Each box costs two wins, and you get 40 tickets total—so mathematically, you can afford two losses and still hit the guarantee . These boxes also contain 8 rewards each, including Hypercharges and Star Powers, so even if you're grinding, you're getting value .

Starr Road

Missed the event? No worries. Starting March 5, 2026, Sirius joins Starr Road for5,500 Creditsor999 Gems. That's the standard Ultra Legendary price tag—same as Kaze .

In-Game Shop

If you're not about that grind life, Sirius is available in the Shop. You can grab him solo for $29.99 or grab the Value Pack for $34.99, which usually bundles him with gadgets and star powers . Limited-time deal, so if you're buying, don't sleep on it.

Sirius's Kit: Understanding the Shadow Mechanic

Before we talk builds, you need to understand how Sirius actually works. His entire playstyle revolves around managing two things: his dual-projectile attack and his shadow collection system.

Main Attack: Binary Starr

Sirius fires two projectiles simultaneously:

• Starr Bomb: A thrown projectile that arcs over walls and deals area damage. Great for pressuring enemies hiding behind cover.
• Shadow Strike: A straight-line projectile that deals single-target damage.

Each projectile deals 1,200 damage at max level. Land both on one ammo, and you're hitting for 2,400 damage—which is massive for a controller . The Star Bomb can be aimed short or long, meaning you can pressure throwers at range or hit close enemies trying to dive you .

Shadow Collection (Unique Trait)

Here's where Sirius gets wild.Every fourth hit on an enemy brawler collects a "Brawler Shadow" . You can store up to three shadows at once. The shadow you collect copies the brawler you hit—so if you've been poking a Frank, you get a Frank shadow with high HP. If you've been hitting an Edgar, you get a mobile assassin shadow .

Super: Shadow Summon

Activating your Super unleashes all collected shadows onto the map . But here's the strategic layer: you can control them.

• Aim your Super:Places a waypoint. Shadows move to that area and guard it, attacking any enemies in range.
• Tap your Super:Recalls shadows to follow and protect you .

This turns Sirius into a mini-RTS commander. You can have shadows holding a Hot Zone, blocking a lane in Brawl Ball, or protecting your gem carrier—all while you poke safely from behind a wall.

Shadow Stats

Shadows aren't full-power copies. They have70% of the original brawler's health and deal55% of their damage. They cannot use Supers, gadgets, or star powers—so no surprise Frank stuns—but they inherit the brawler's attack mechanics. A Kenji or Edgar shadow can still heal, making them surprisingly durable . You can have up to six shadows active at once, which is absolute chaos in team fights .

Hypercharge: Unlimited Power!

Sirius's Hypercharge buffs any shadows summoned during its duration. They get8 5% health and 70% damage of the original brawler—significantly stronger than base shadows . Sirius himself gets a 20% speed boost, 5% damage boost, and 5% shield . The Hypercharge takes a while to charge, so save it for major team fights or when you're pushing a critical objective .

Best Sirius Build: Star Powers, Gadgets, and Gears

After analyzing top player builds and competitive data, here's the optimal setup for Sirius. This build maximizes your shadow generation, pressure, and survivability across most game modes .

Best Gadget: A Starr is Born (55% pick rate)

This gadget fires a projectile that summons a shadow on hit and slows the target by 20% for 2 seconds . Why is this better than Master of Shadows? Simple: immediate value. You don't need shadows collected—you just need to land a shot. Use it to:

• Create a shadow instantly when your bar isn't charged
• Slow escaping enemies so your team can finish them
• Generate pressure out of nowhere

Cooldown: 17 seconds. This is why the Gadget Cooldown Gear matters.

Alternative: Master of Shadows (recalls and heals shadows) has its fans—it's great for keeping your army alive in prolonged fights . But A Starr is Born gives you more flexibility and instant impact, which is why 55% of players prefer it .

Best Star Power: The Darkest Starr (82% pick rate)

This is non-negotiable. Each Shadow Strike hit counts as 2 toward shadow collection instead of 1. That means:

• Normally: 3 hits = 1 shadow bar
• With Darkest Starr: 3 successful dual-projectile connections can nearly fill2 bars

You generate shadows twice as fast. In a meta where tempo matters, reaching your pressure state before your opponent is ready wins games .

Alternative: Dusk Runners gives shadows +15% movement speed . It's decent for chase-down potential, but faster shadow generation is almost always better for map control.

Best Gears

Gear 1: Gadget Cooldown (must-have)

A Starr is Born has a 17-second cooldown. Gadget Cooldown Gear reduces that significantly, letting you create shadows more frequently and maintain constant pressure .

Gear 2: Damage or Shield

• Damage Gear:+15% damage below 50% HP. Sirius lacks burst damage on his own, so this helps you win those low-health duels .
• Shield Gear:+900 HP as a consumable shield. Great for survivability when you're caught without shadows .

Pick Damage if you're confident in your positioning; pick Shield if you find yourself getting dove by assassins.

Best Game Modes for Sirius

Sirius performs well in most modes, but he absolutely dominates in objective-based maps where area control matters.

Hot Zone (Best Mode)

This is Sirius's playground. Summon shadows directly into the zone to annoy enemies and force them to waste ammo . Use your Starr Bomb to hit enemies hiding around the zone. Shadows can't capture the zone, but they can defend it by attacking anyone who steps in . A well-timed Super here decides the match.

Heist

Your shadows deal solid damage to the safe while also acting as a shield against defenders . Stay at range, poke with your main attack, and let your army do work. Smart players can use shadows to block incoming attackers while pulverizing the safe .

Gem Grab

Control the center with your shadows . Place them at choke points where enemies need to push for gems. Support your gem carrier by slowing enemies with your gadget and poking from behind walls .

Brawl Ball

Shadows can block enemy pushes and guard your ball carrier . Place them in lanes where enemies will run.Important:You cannot pick up the ball while shadows are active, so time your Super around your team's plays .

Bounty

Sirius works well here because many snipers lack escape mechanics—just like him . Your shadows do the heavy lifting while you stay safe. Plus, you can attack over walls, which helps against camping Pipers .

Showdown

Duo and Trio Showdown are great for Sirius. Shadows help destroy boxes, keep enemies at bay, and shield you from damage .

Best Teammates for Sirius

Sirius thrives with teammates who either protect him while he farms shadows or capitalize on the chaos his shadows create.

Pro Tips for Mastering Sirius

Stack Before You Summon

Try to collect2-3 shadowsbefore using your Super . Summoning multiple shadows at once creates a much bigger threat and forces enemies to deal with multiple problems simultaneously.

Control Your Shadows Like a General

Don't just summon and forget. Use your Super toplace shadows in choke points, lanes, or objectives. In Gem Grab, park them where enemies need to walk to reach the mine. In Brawl Ball, have them guard your carrier or block the enemy's scoring path . Smart placement wins games.

Use Walls

Sirius is a thrower at heart.Abuse walls. The Starr Bomb goes over them, so you can safely poke enemies hiding behind cover. Stay behind walls, peek to line up your Shadow Strike, and duck back. This keeps you healthy while you build shadows .

Save Hypercharge for Big Fights

Hypercharge takes a long time to charge. Don't waste it on small skirmishes.Pop it when you already have 3 shadows ready, summon your buffed army, and watch the enemy team melt . The stats jump from 55% to 70% damage and 70% to 85% health is massive .

Auto-Aim in Emergencies

If an assassin dives you,auto-aim is your friend. It charges your shadow bar and Hypercharge quickly. Even if you die, you might have set up a massive counter-push for your team.

Know Your Counters

Sirius struggles against:

• Crow: His poison negates healing mechanics—hard counter .
• Long-range snipers (Piper, Mandy):They outrange you. Position carefully .
• Edgar/Leon: No escape mechanics means you're dead meat if they reach you without shadows .

Final Thoughts: Is Sirius Worth It?

If you're the type of player who loves strategic depth, map control, and forcing enemies into uncomfortable positions, Sirius is one of the most rewarding brawlers in the game. He's not a point-and-click burst damage dealer—he's a commander who wins through pressure and positioning. Yes, his mechanics take time to master. Yes, you'll have games where you feel useless because you couldn't build shadows. But once you understand his rhythm, Sirius can completely reshape how a match is played .

He's currently considered S-Tier by many analysts, and with good reason—his shadow mechanic is unlike anything else in the game . Whether you're grinding trophies or pushing ranked, Sirius is worth the investment.

Good luck out there, and happy brawling~~!
